Abstract

In vitro wood slats degradation assays reveal that both the white root rot fungus R. lignosus and the brown root rot fungus P. noxius cause a white rot of wood. In vivo (infected tap roots) they cause the same type of decay. Nevertheless lignin determination show the rubber-tree ability to react against the parasite aggression by increased lignification of tissues.
